Which screen provides a chronological record of events, alarms, and faults for troubleshooting?

• A. Alarm Screen.
• B. Fault History Screen.
• C. Event Log Screen.
• D. Diagnostics Screen.

Answer: (C)

Tracking what happened and when is essential for debugging. The Event Log Screen is built to capture a chronological sequence of actions, alarms, and faults with time stamps, giving you a clear timeline to see the order of events and how they relate to each other. This makes it possible to trace back to the moment something went wrong and identify potential causes.

Alarms shown on the Alarm Screen are current and active, not a complete history. The Fault History Screen focuses on past faults but may not include every event or the real-time context. The Diagnostics Screen provides system health and status information rather than a full event timeline.

So, for a trustworthy, time-ordered record used in troubleshooting, the Event Log Screen is the best fit.
